BALANCED LATHE DOG

**natie123** · Sep 10, 2018, 05:47 AM

I needed a lathe dog to drive a between-centers boring bar. Not wanting to fiddle with balance weights, I made this balanced version that has two drive pins (Photos 1 - 3).
The bars are 12x12 mm square bar with a “V” cut in the middle to suit the diameter of the stock to be driven by the dog. Mine should work for diameters of 12 – 50 mm. A 10 mm round bar drive pin was welded on near the end of each bar and the two sections are held together with M6 hex-socket bolts (Photo 4). The design can be scaled up or down as required. In use the lathe dog and boring bar assembly runs smoothly with no discernable vibration.

Nice! Simple and nice, and seems quite scalable
